Abnormal temperature and excessive concentration of harmful gases inside the car not only affect the comfort of drivers and passengers, but may also pose a serious threat to their health and even life safety. Therefore, it is of great significance to develop a system that can monitor the in car environment in real time and accurately, and has automatic protection functions.This design proposes a car interior environment monitoring system based on STM32F103C8T6 microcontroller. The main functions of the system include: detecting whether there is a person in the current car through the D203S human detection module; Use DS18B20 temperature detection module to detect the temperature of the current environment; Use MQ-3 to detect the current alcohol content inside the car; Detect the current CO content inside the vehicle through MQ-7. When someone is detected inside the car and the temperature is above the maximum value, or the alcohol concentration is above the maximum value, or the CO concentration is above the maximum value, the system controls the four phase five wire stepper motor through the ULN2003A chip to automatically control the windows to open, and at the same time, sound and light alarms are triggered, and voice reminders are provided through the CN-TTS voice broadcast module; If the temperature is below the minimum value, only sound and light alarms and voice reminders will be given, and the car windows will not be opened. Users can set the maximum alcohol value, maximum CO value, as well as the maximum and minimum temperature values through buttons; The system displays various measurement data in real-time through an OLED display screen; In addition, the system sends measurement data to the mobile phone through the ECBO2 Bluetooth module, which can set various thresholds and remotely control the opening and closing of car windows.The function of the in car environment monitoring system is to provide comprehensive safety protection for drivers and passengers in the car environment. Through real-time monitoring, automatic response, and remote control, abnormal situations in the car environment can be detected and handled in a timely manner, effectively reducing safety risks and improving driving safety and comfort.Keywordsmicrocontroller; Vehicle interior environment monitoring; STM32F103C8T6 Gas detection; Remote control目 录1 绪论1.1 研究背景及意义1.2 国内外研究现状1.3 主要内容2 系统总体方案设计2.1系统总体设计2.2 主要模块方案选择3系统硬件设计3.1 总体硬件框架3.2 主控模块电路设计3.3 人体检测模块电路设计3.4 温度检测模块电路设计3.5 酒精检测模块电路设计3.6 CO 检测模块电路设计3.7 车窗控制模块电路设计3.8 声光报警模块电路设计3.9 语音播报模块电路设计3.10 显示模块电路设计3.11 按键模块电路设计3.12 蓝牙模块电路设计4 系统程序设计4.1 编程软件介绍4.2 系统主流程设计4.3 独立按键4.4 OLED显示流程设计4.5 温度检测模块子流程4.6 步进电机子流程设计4.7 语音播报模块子流程设计4.8 蓝牙模块子流程设计5实物制作与功能测试5.1 实物制作5.2 环境参数检测及显示功能测试5.3 异常报警及车窗控制功能测试5.4 参数设置功能测试5.5 蓝牙数据传输及远程控制功能测试6 总结参考文献致谢附录A 原理图附录B PCB附录C 主程序
